Answer:
B. 34.78 m/s
Explanation:
Momentum of a body or an object is given as the product of its velocity and its mass.
Therefore;
Momentum= velocity x mass
But; velocity = ? mass =115 kg , momentum = 4,000 kgm/s
Thus; velocity= momentum/mass
= 4,000/115
= 34.78 m/s
Answer:
Explanation:
From the question we are told that:
Altitude 
Mass 
Radius 
Generally the equation for Satellite Speed is mathematically given by
Therefore
Period T is Given as
Answer:
0.303s
Explanation:
horizontal distance travel = 2.050 m, vertical distance travel = 0.45 m
Using equation of linear motion
Sy = Uy t + 1/2 gt² Uy is the inital vertical component of the velocity, t is the time taken for the vertical motion in seconds, and S is the vertical distance traveled, taken downward vertical motion as negative
-0.45 = 0 - 0.5 × 9.81×t²
0.45 / (0.5 × 9.81) = t²
t = √0.0917 = 0.303 s
I am 99999.999999999% sure that it is his second law of motion.
